Description:
OBJECTS OF THE INVENTION
It is an object of the invention to provide an improved spare wheel and tongue truck combination for a trailer or the like.
Another object of the invention is to provide an improved combination trailer and tongue truck.
Another object of the invention is to provide a tongue truck which is simple in construction, economical to manufacture, and simple and efficient to use.
DESCRIPTION OF THE DRAWINGS
FIG. 1 is a top view of the trailer tongue and tongue truck according to the invention.
FIG. 2 is a side view of the trailer tongue and truck with the wheel shown in stowed position.
DETAILED DESCRIPTION OF THE DRAWINGS
Now with more particular reference to the drawings, a trailer tongue 10 is shown which is intended to be the tongue of a two-wheel trailer such as a house trailer, box trailer, boat trailer type or the like. The tongue has a carrying rack 11 attached to it and a wheel mount 12 attached in spaced relation to the carrying rack. The wheel mount 12 has a wheel 13 with a tire 14 supported in the fork 15. The fork has a fork plate 27 which is pinned and swingably supported by pin 17 to the lock plate 16. The lock plate 16 has two spaced holes which receive pins 17 and 18. When the pin 18 is removed, the wheel and fork can be swung to the position shown in full lines in FIGS. 1 and 2. When the wheel is swung down to the position shown in phantom lines, the plate 16 can be swung around the swivel joint 28 so that the wheel can be used as a tongue truck. The plate 26 of the fifth wheel is clamped to the tongue by means of bolts 19 and nuts 22 on them and a bearing material 30 is disposed between the plate 26 and the plate 16 so that the two can rotate relative to each other. Plates 16 and 26 make up a fifth wheel. It will be noted that the swivel joint 28 is disposed off center toward the front in the plates 26 and 16 so that a castering effect is accomplished. The plate 12 may be considered to be an attachment plate. The carrying rack 11 has bolts 21 which have nuts 23 on them that hold the carrying rack 11. Pins 31 are disposed at each side of the carrying rack in the channel member 32 and when the cotter pins 22 are removed, the entire tire can be swung down and laterally out of the carrying rack. Wheel 13 has the usual hub 34 and suitable bearings which are familiar to those skilled in the art.
It will be noted that when the wheel is in the rack position shown in FIG. 2, the trailer can be towed by a suitable tractor vehicle. When the wheel is swung down to the phantom line position, the pin 18 can be replaced and the wheels pivoted as a caster around swivel joint 28 so that it will act as a tongue truck for the trailer.
The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.
